(old?) sa hang @ "bayes: can't use estimation method for expiry"

Hi,

I'm updating SA & exploring/cleaning Bayes DBs on a slighty 'dusty' box.

after update to latest SA 32x-branch, --lint is OK.

but, currently, i get:

sa-learn --force-expire -D

	...

	[19416] dbg: bayes: found bayes db version 3
	[19416] dbg: bayes: opportunistic call attempt skipped, found fresh

where it just 'sits' for awhile -- no errors in logs -- and, eventually, 'releases' and completes without error.

this only seems to happen an unquantified "some of the time" ... sometimes (as moments ago) repeating the process results in no such hand/delay.

fyi,

i had NOT noticed this before on this box ... not clear if it's the build or my local.cf's bayes-related settings. or, perms, maybe?

i've found some old thread references to

  "[19416] dbg: bayes: can't use estimation method for expiry, unexpected    result, calculating optimal atime delta (first pass)"
